Upper limb prostheses are devices used to support activities of daily living in individuals whose arm and hand have been partially or completely lost or are congenitally absent; these applications are covered under the heading arm and hand prostheses. Prosthesis selection and fitting are planned in line with the specialist physician's assessment and prescription.
Types of Prostheses
These devices can also be classified using the approach of upper limb prostheses by amputation level. Upper limb prostheses are generally examined in the following groups:
- Body-powered prostheses: Prostheses in which movement is provided through a cable system using force from body regions such as the shoulder and trunk. Their structure is relatively simple.
- Myoelectric prostheses: Electronic prostheses that provide movement by detecting muscle signals with electrodes placed on the skin surface; their working principle is detailed under myoelectric arm prostheses. They may offer more natural control; their use and maintenance requirements are more extensive.
- Hybrid prostheses: Prostheses that combine body-powered and myoelectric systems, planned according to the individual's needs.
Main Components
The main parts of upper limb prostheses are:
- Socket (body): The part in contact with the body, custom-designed, which determines how the prosthesis fits.
- Suspension system: Mechanisms such as straps or vacuum that secure the prosthesis to the body.
- Terminal device: The part at the end of the prosthesis that supports functions such as grasping.
Adaptation and Care Process
Prosthesis fitting covers the stages of measurement and assessment, socket preparation, assembly and fitting. During these stages, user training is provided with the support of the rehabilitation team. Regular cleaning and periodic check-ups of the prosthesis contribute to appropriate use of the device. Selection, fitting and adjustment of the device are carried out in line with the relevant specialist physician's medical report.
